meditation. the guru meditated in his empty school for several hours. suddenly, he had a vision of the number [php]$combination = rand(1,3);if ($combination == 1) echo 3;if ($combination == 2) echo 8;if ($combination == 3) echo 7;[/php]. he knew this number must have some significance. he thought about it for several more hours, but he could not figure it out. should he read his scrolls or return to the village square.
